I tried to search for this but it's not easy..

Anyway, I just so happen to have a 76 crew cab with the old hydro assist steering and was wondering if anyone knows if this can be used with a newer (79) tapped box for hydro assist? What do people usually run for the rams?

im not sure if it would be powerful enough, as it wasnt so great in its stock power assist form. most people run regular ass tie rod end hydraulic cylinders. either 6'' - 8'' of stroke and 1.5'' - 2.0'' bore depending on the setup.

bigger the bore, the slower steering response and it can get a little hairy on the street, i know from experience, there is a dented up chevy that could tell you.:)

I thought about this too and all the information I read on these things was that they leaked like a sieve from the factory and they weren't very reliable. Better to get a modern ram, etc.

Ah, I didn't realize it was the ram that leaked, I thought it was something in the box. I see kits are only about $200 so I'll probly just go that route at some point.
